Document missing commands from ProductAsset and RuleEngine bundles [EE]

[mickaelandrieu]

Hello,

I've been noticed that a lot of commands are not documented right now. I think we can do something with that, maybe with 1 or 2 cookbooks introducing a task to do and how theses commands can help.

We are talking about these commands:

• pim:asset:generate-missing-variation-files
• pim:asset:generate-variation-files-from-reference
• pim:asset:generate-variation-file
• akeneo:rule:run
• others from RuleEngine bundle?
